Manufacturing method capable of effectively improving product life of capacitor

Abstract

The invention discloses a manufacturing method capable of effectively improving product life of a capacitor, which comprises the following manufacturing steps of: first step: winding; second step: hotpressing; third step: metal spraying; fourth step: energizing; fifth step: testing; sixth step: welding and assembling; seventh step: filling; and eighth step: final product testing. The method is characterized in that a heat treatment step is further included between the second step: hot pressing and the third step: metal spraying, and a second heat treatment step and second testing are furtherincluded between the fifth step: testing and the sixth step: welding and assembling. The method mainly aims at a motor capacitor which is subjected to heat treatment process after finishing the primary winding and hot pressing so as to remove moisture inside a core and stabilize product capacity; and after the test step, the product is subjected to heat treatment, thereby improving the product life.

Description

technical field [0001] The invention relates to a production method, in particular to a production method which can effectively improve the service life of capacitor products. Background technique [0002] Unlike most electrical equipment, motor capacitors are not connected to the power system as stand-alone devices. In each case, the capacitors are connected in series with the induction winding and may be in direct contact with the motor or other equipment, so the performance of the motor and these other equipment It has a great impact on the operation of the capacitor, so it is necessary to fully consider these factors in the process of making the capacitor, so as to prolong the life of the product. figure 1 It is a schematic diagram of the commonly used production method at present, mainly including the following steps: winding, hot pressing, gold spraying, energizing, testing, welding, assembly, pouring, and finished product testing. After the hot pressing is completed b...

[0002] Unlike most electrical equipment, motor capacitors are not connected to the power system as stand-alone devices. In each case, the capacitors are connected in series with the induction winding and may be in direct contact with the motor or other equipment, so the performance of the motor and these other equipment It has a great impact on the operation of the capacitor, so it is necessary to fully consider these factors in the process of making the capacitor, so as to prolong the life of the product. figure 1 It is a schematic diagram of the commonly used production method at present, mainly including the following steps: winding, hot pressing, gold spraying, energizing, testing, welding, assembly, pouring, and finished product testing. After the hot pressing is completed by this method, there is no heat treatment. Capacitors If the moisture inside the core is not discharged in time, it is easy to cause unstable product quality and short service life
